EXTENSIBLE-SHADE TRIMMER.

Specification of Letters Patent.

Application filed December 9, 1907.

Patented March 30, 1909.

Serial N0. 405,756.

To all whom it may concern:

Be it known that I, Humane S. WALT/J, a citizen of the United States, residing at Medina, in the county of Medina and State of Ohio, have invented certain new and useful Improvements in Extensible-Shade Trimmers, and do declare that the following is a full, clear, and exact description of the invention, which will. enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an extensible shade trimmer, all substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a plan view of the trimmer and Fig. 2 is an end view thereof, looking from the left of Fig. 1. Fig. 3 is an end view from the right of Fig. 1. Fig. l is a longitudinal sectional elevation of the invention with the parts reversed as compared with Fig. l.

The device or machine as thus shown is designed to trim standard or stock shades to fit particular windows, and may be used in the store or shop where the shades are sold and made up in widths according to measures furnished, or the device may be taken to the dwelling or building where the shades are to be put up, so as to trim each shade according as a given window may require.

To these ends the device comprises a suit able base 13, say a board of a suitable length and width, upon which the operatin parts are mounted. These parts consist o a rectangular tube S supported from or upon said base between standards or posts C fixed on base B, and said tube is adapted to be adjusted and set in said standards according to the width of shade to be trimmed.

In Fig. l the trimming is shown to be at the right, and a sharp blade, cutter or knife K is fixed upon base B at its front end and the shade is adjusted in respect thereto according to the width it is to have and as much of a strip 2 is cut therefrom as the shade may require. The shade E is first rolled upon its own roller It, which is engaged at its ends in the usual ears or brackets 3 and 4, and these are fixed as shown in Fig. 1., the bracket 3 on sleeve S and the bracket 4 on bar D. Said bar is slidab'ly and adjustably supported in tube S and adapted to project from one end thereof more or ard width being indicated by the scale 8 on said bar and marked 37, 2:58 and the like. Another scale 10 is provided on tube S, and a pointer 12 or its equivalent is provided on one of the standards U to guide the setting of the parts to this scale, by which the width to which the shade is to be trimmed is accurately determined. The scale 8 tells the original width of the shade, and when this is ascertained the bar D and tube S are locked together by thumb screw, said parts are then moved bodily and together in said standard and the reduced width wanted, if any, is gaged on scale 10 and then set screw 6 is tightened on tube S and the parts are temporarily locked. The standards or posts U have lips or flanges at their top overlapping tube S somewhat, excepting standard C at the left and front of Fig. l, and shown in Fig. 2 which is short enough to permit the shade supporting ear or bracket 4 to pass over the same in the longitudinal adjustment of parts S and D in making narrow shades. After a shade has been narrowed the shade roller is cut off at one end to correspond to the reduced width and its roller point or spindle fastened thereon again as before, and it is then ready to be hung for use.

It will be seen that blade or knife K is formed with a segmentally curved edge, terminating at its highest point, which adapts it to cut the doubled lower edge 14 of the shade E as clearly and sharply as with a pair of shears, and the peculiar construction of the knife enables this to be done.

Fig. t shows the parts C, D and S, as they appear in Fig. l except that the parts D and S are reversed as to their ends, and they may be worked either way.

\Vhat I claim is l. A portable shade trimming device comprising two shade supporting members extensibly mounted one within the other, and a base provided with brackets in which said supporting members are adjustabl y mounted, and a shade trimming blade fixed upon one end of said base, in combination with shade supporting brackets on opposite ends respectively of said shade supporting members.
